I take a lot of faith in the following:
The terrorists have their plans, and we have our plans.
But God has a plan too....and it is yet to be seen. Evil has a reign, but it ends abruptly and often with terrible consequences to evildoers.
And God sometimes uses people to accomplish his plans. I just hope I am lucky enough to be part of the instrument of their destruction when it happens.
Ditto and Amen.
